PRUNING IMPLEMENT.

Application filed Ml, 6,1907. Serial No. 372.230.

Specification of Letters Patent.

Patented Oct. 15, 1907.

To all whom it may concern:

Be it known that 1, CHARLES E. CRoMBIE, a citizen of the United States,residing at Manchester, in the county of Hillsboro and State of NewHampshire, have invented certain new and useful Improvements in PruningImplements, of which the following is a specilication.

My invention relates to certain new and useful improvements in pruningimplements and the object of my invention is to produce an implement ofthis class which shall be cheap to construct, composed of few parts,powerful and simple in its operation, and durable.

With these and other objects in view my invention consists in certainconstructions, combinations and arrangements of parts the preferred formof which will be first described in connection with the accompanyingdrawings and then the invention particularly pointed out in the appendedclaims.

Referring to the drawings wherein I show the preferred form of myinvention and wherein the same part is designated by the same referencenumeral wherever it occurs Figure 1 is a perspective view of a pruningimplement embodying my invention, Fig. 2 is a section on line 22 of Fig.1, Fig. 3 is a front edge view, Fig. 4 is a detail section on line 44 ofFig. 1, and Fig. 5 is a cross section of the staff through the lever.

1 designates a staff of any suitable or desired length in the upper endof which is cut a kerf 2, 3 designates a hooked member havinga shank 4,a nose 5 and a cutting edge 6 on the inner edge of the nose portion. Thehooked member is secured to the staff 1 by placing the end of the shankin the kerf 2 and passing rivets 7 or other securing devices through thestaff and suitable openings in the shank.

S is an arm pivoted at 9 to the member 3. The edge of this arm at l0 isground down on the outside to form a cutting edge to coact with the edge6 of the nose 5. Preferably, and as shown, the edge 6 is formed by asharp bevel while the edge 10 tapers gradually back.

11 designates a coil spring one end of which is secured to the arm 8 andthe other end to the hooked member 3 near its upper end whereby thecutting edges will be I normally held apart.

l2 designates an operating lever pivoted at 13 in a slot 14 cut in theside of the staff near its lower end. 15 designates a pair of plates onesecured to each side of the slot between which the lever 12 works. i

. l6 designates a plate provided with a slot 17. This plate is securedon the side of the staff and over the slot 14 with the lever passingthrough the slot 17 whereby the movement of the lever is limited and theenlarging of slot 14 prevented.

1S designates a wire one end of which is connected to the lever 12 andthe other end to the arm 8 whereby power applied to the lever 12 istransmitted to the arm.

It will be noted that the nose 5 tapers down to a point and that thecutting edge 6 on the inner edge thereof is substantially parallel tothe staff 1. It will also be noted that the edge 19 of the shank formsan acute angle with the cutting edge 6 and alsothat when the parts are Lin open position the cutting edge 1.0 of the arm 8 stands entirelybehind the shank portion. It is also to be noted that by giving the arm8 the curve shown it extends up from the staff and the device cantherefore be pushed up through the branches with less difliculty. It isalso to be observed that by having the edge 6 extend substantiallyparallel to the body of the staff there will not be the tendency for thedevice to lift and slip during the cutting operation that there wouldotherwise be.

What I claim as new and desire to secure by Letters Patent is:

1. A pruning implement, comprising a staff, a hooked portion mounted atone end of the staff, said hooked portion comprising a nose. and a shankportion. a cutting edge formed on the edge of the nose adjacent to theshank portion, the cutting edge extending substantially parallel to thestaff, an arm pivoted to the hooked member said arm having a cuttingedge on one side of the pivot with the portion of the arm on the otherside of the pivot adapted to extend substantially in line with thestalfwhen in normal position, a spring connected to the hooked member and thearm to hold the arm in its normal position, an actuating lever pivotedon the staff and a connection between the lever and the arm.

2. A pruning implement, comprising a staff, a hooked portion mounted atone end of the staff, said hooked por tion comprising a nose and a shankportion, a cutting edge formed on the edge of the nose adjacent to theshank portion, an arm pivoted to the hooked member, said arm having acutting edge on one side of the pivot with the portion 01. the arm onthe other side of the pivot adapted to extend substantially in line withthe staff when in normal position, a spring connected to the hookedmember and the arm to hold the arm in its normal position, an actuatinglever pivoted on the staff, and a connection be tween the lever and thearm.

3. A pruning implement, comprising a staff, a hooked portion mounted atone end of the staff, said hook portion comprising a nose, and a shankportion, a cutting edge formed on the edge of the nose adjacent to theshank portion, the cutting edge extending substantially parallel to thestaff, an arm pivoted to the hooked member, said arm having a cuttingedge on one side of the pivot which is adapted to stand behind the edgeof the shank when the parts are in their normal position, a springconnected to the hooked member and the arm to hold the arm in its normalposition, an actuating lever pivoted on the staff and a connectionbetween the lever and the arm.

In testimony whereof I atfix my signature in presence of two witnesses.
